giffgaff referral code

Get £5 giffgaff credit when you activate a new SIM using a refer-a-friend link.

giffgaff's refer-a-friend scheme gives the new customer £5 free credit once they activate their SIM with a goodybag, while the referrer earns £5 in Payback — cashable via PayPal, kept as credit, or donated — paid out every six months. I've been with giffgaff since 2011, and the £5 has landed for me and for the friends I've referred over the years.

How giffgaff compares to other mobile networks

giffgaff is cheaper per GB than VOXI but lacks unlimited social media data. Same O2 network as going direct but at lower prices. Trustpilot score of 4.1 beats VOXI (2.9) and is comparable to SMARTY (4.3).

giffgaff competes most directly with VOXI, SMARTY, and Lebara in the budget SIM-only space. Compared to VOXI, giffgaff is typically cheaper per GB but lacks the unlimited social media data perk. SMARTY (on the Three network) offers similar pricing and flexibility. Lebara is competitive on international calling but has a smaller UK footprint. Compared to going directly with O2, giffgaff offers the same network at significantly lower prices — the trade-off is that you lose access to O2 Priority rewards and in-store support. giffgaff's Trustpilot score of 4.1 is strong for a mobile network.
